Party of the Mexican Revolution

The Party of the Mexican Revolution (PRM) was a social democratic political party in Mexico that existed from 30 March 1938 to 18 January 1946. The party was founded by Lazaro Cardenas, who was formerly the leader of the National Revolutionary Party of Mexico (PNR). Cardenas was picked by liberal PNR leaders as the candidate, opposing his conservative mentor Plutarco Elias Calles, who had turned against the people and the labor unions. Cardenas renamed the PNR to the "PRM" and returned the party to its social democratic roots, and the PRM nationalized the oil industry in Mexico and redistributed land to the peasants. The party became a very popular one, and it was later renamed to the "Institutional Revolutionary Party" in 1946.
